ESPsoup Beta 0.4

ESPsoup public beta 0.4 (app version 0.12.15) — receive-only radio scanner for the ESP32-C5, now with an experimental 60 GHz radar tool and RTL-SDR / PlutoSDR support.

Install (Android 7+): download ESPsoup-beta-0.4.apk (5.1 MB), allow installing from this source, plug an ESP32-C5 into the phone with a USB-OTG adapter — use the board's native USB port, not the UART/CH340 port. Updating from beta 0.1/0.2/0.3 keeps your settings.

What's new in 0.4

Area	New	Status
📡 60 GHz radar (new tool)	With the Seeed Studio MR60BHA2 kit (XIAO ESP32-C6 + HLK-LD6002 60 GHz radar) and the new ESPsoup radar firmware: presence, distance, target position with trail, point cloud, breathing and heart rate (person sitting still 0.4–1.5 m away), live charts (vital signs, distance, phase), top-down view, detection-zone settings, optional floating radar overlay on the spectrum / waterfall. Only shown while the radar firmware is connected	◐ experimental · needs the MR60BHA2 kit, the ESP32-C5 can't do this
🔧 Firmware installer	Device → Firmware now offers the right firmware per chip: ESP32-C5 → ESPsoup firmware 0.7.1, ESP32-C6 → ESPsoup radar firmware 0.7.2; backup first and every write verified, as before. C6 boards no longer get the "update to 0.7.1" hint	✅
📻 External SDRs	RTL-SDR and PlutoSDR added: over WebUSB in desktop Chrome / Edge — receiver picker, live spectrum and waterfall	◐ spectrum and waterfall only · decoders still need the ESP32 · not on Android yet
🔍 Find	Automatic close-range gain cut in 10 dB steps with a tone hint, "body shadow" bearing toggle, direction arrow to the estimate, suggested next measuring point, terrain-aware location estimate	✅
🗺️ Offline map	Save OpenStreetMap tiles and terrain around you and use them without internet (e.g. in airplane mode)	✅
🐞 Diagnostics	REC button for a diagnostics recording: one .tar with events, spectra and SigMF I/Q to attach to a bug report	✅
📶 Mobile networks	Picker in Spectrum: operator uplink / downlink blocks per EU country, one tap to tune	✅
🏷️ Vendor lookup	Manufacturer names (IEEE) for Wi-Fi and Bluetooth MAC addresses	✅
🕵️ Fewer false finds	Spur rejection in the camera / bug finder and in Scan (spur mask per board + retune check)	✅
🔎 Scan	"Clear finds" button (tap twice); searches keep running until you stop them	✅
🌍 Languages	All radar and installer texts in all 23 languages	✅
🛠️ Fixes	ANT decoder no longer throws on malformed data; new attributions (IEEE OUI, Bluetooth SIG company IDs, OpenStreetMap, Mapzen / AWS Terrain Tiles, mobile band data) in THIRD_PARTY.md	✅

Hardware for the radar: the 60 GHz radar tool needs the Seeed Studio MR60BHA2 60 GHz mmWave kit (XIAO ESP32-C6 + HLK-LD6002 radar) — https://espsoup.com/go/mr60bha2 . It is not a receiver for the other tools; the ESP32-C5 stays your main board.

Firmware:

• ESP32-C5: unchanged — the app installs the ESPsoup firmware 0.7.1 (GPL-3.0-or-later, a fork of ESP-SDR by ESPARGOS). Its complete source code is attached (espsoup-firmware-0.7.1-source.tar.gz).
• ESP32-C6 (MR60BHA2 kit): new ESPsoup radar firmware 0.7.2 (GPL-3.0-or-later, a fork of the ESPsoup firmware) — receive-only ESP-SDR plus a link to the kit's radar module. Install it from the app (Device → Firmware, backup first, every write verified) or with esptool. Its complete source code is attached (mr60bha2-sdr-firmware-0.7.2-source.tar.gz).

Beta: expect rough edges; the radar tool is experimental and its vital signs are not medical measurements. ESPsoup only receives (the MR60BHA2 radar module itself emits 60 GHz, as every radar sensor does); rules on receiving radio signals differ between countries.
